如果我在 ScrollView 中执行 LayoutTransition(动画是在 LinearLayout 上完成的),它会很好地扩展。但是,如果我删除某些东西,那么在动画繁忙的时候,一切都会被推上去,这看起来很难看。它与这个问题有些相同:LayoutTransition:2 个容器
这是我的xml:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:animateLayoutChanges="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/card"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin">
<View
android:layout_width="match_parent"
android:layout_height="5dp"
android:layout_gravity="left"
android:layout_marginRight="1dp"
android:background="#00000000"/>
<Button
style="?android:attr/spinnerStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:layout_marginTop="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"/>
<Button
style="?android:attr/spinnerStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="@dimen/activity_vertical_margin"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:ems="10"
android:gravity="start"
android:hint="@string/addassignment_description_hint"
android:inputType="textMultiLine|textCapSentences"
android:minLines="3"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="@dimen/activity_vertical_margin"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:textColor="@android:color/white"/>
</LinearLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<com.google.android.gms.ads.AdView
android:id="@+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="@android:color/black"
ads:adSize="SMART_BANNER"
ads:adUnitId="@string/ad_unit_id"/>
</FrameLayout>
</LinearLayout>
</ScrollView>
有没有人知道如何使用 LinearLayout 使 ScrollView 动画效果很好?
